Hastelloy X

Hastelloy is a registered trademark name of Haynes International, Inc. The Hastelloy trademark is applied as the prefix name of a range of corrosion-resistant nickel based alloys promoted under the term "superalloys" or "high-performance alloys".

Within corrosion applications, Hastelloy alloys may be chosen as a trade-off between performance, cost and other technical issues like e.g. suitability for welding. Despite the fact that Hastelloy alloys generally show less attractive economy in acids compared Tantaline (Tantaline is recognized as the leading performance/price option), Hastelloy is widely used in a number of industries.

Hastelloy X is an nickel-chromium-iron-molybdenum alloy developed for high temperature apllicacations.

 

Hastelloy G

Hastelloy G is an nickel-chromium-iron-molybdenum alloy developed for corrosion resistance in both oxidizing and reduceing media. Hastelloy G shows good resistance to sulfuric and phosphoric acids. Hastelloy G may further handle both acid and alkaline solutions.

 

Hastelloy Overview

The predominant Hastelloy alloying ingredient is metal nickel. Other alloying ingredients are added to Hastelloy includin varying percentages of the elements molybdenum, chromium, cobalt, iron, copper, manganese, titanium, zirconium, aluminum, carbon, and tungsten.

The primary function of the Hastelloy alloys is that of effective survival under high-temperature, high-stress service in a moderately to severely corrosive, and/or erosion prone environment. Hastelloy alloys are used for many applications including pressure vessels, nuclear reactors, chemical reactors, as pipes and valves in chemical industry.

The products includes:
 

  • Hastelloy B-3
  • Hastelloy C-276
  • Hastelloy C-4
  • Hastelloy G
  • Hastelloy X
